Perrantes hit all four of his 3-point attempts and Malcolm Brogdon also scored 15 points for Virginia (24-5, 15-1 Atlantic Coast Conference). The victory was Virginia's school-record 17th straight at home in conference play and assured them of one of the top two seeds in next month's conference tournament.
Erik Swoope scored 13 points and Rion Brown had 12 for Miami (14-14, 5-10). The defending ACC regular season and tournament champions shot just 26 percent (12 of 46) and had their modest two-game winning streak snapped.
It happened, as it has so often this season for Virginia, with a big burst.
Leading 27-20 at halftime, Virginia got two 3-pointers from Perrantes in the 16-5 spree after intermission. Brogdon scored four points and Akil Mitchell had a three-point play in the run, which was helped along by a scoreless string of nearly 4 1-2 minutes by the Hurricanes.
Davon Reed ended that with a basket in the lane, moments after he had airballed a free throw, but instead of the Hurricanes making a game of it, Virginia pulled away, leading by as many as 26 points.
It was Virginia's 11th ACC victory by double digits, and most of them were over early.
Virginia used an early 10-2 run to open a 15-10 lead, and led 27-20 at halftime. Both teams shot poorly in the half, with Virginia making only 9 of 27 shots (33 percent), but five were 3-pointers. Miami was 8 for 25 in the half (32 percent) and missed all seven of its 3-point tries.
